Some cytokines are pro-inflammatory, but others are anti-inflammatory (3). The anti-inflammatory interleukins comprise interleukine-4 (IL-4) and interleukine-10 (IL-10) and these are considered as mediating the down-regulation of immune-inflammatory conditions. Acupuncture for treatment of the ulcerative colitis rats is possibly related with the decrease of IL-1β, a pro-inflammatory cytokine, and the increase of IL-4, an anti-inflammatory cytokine (15).
